+3.     Definitions
+
+3.1    Explanation of NEW definitions in:
+
+       include/configs/MPC8313ERDB.h
+
+       CONFIG_MPC83xx          MPC83xx family
+       CONFIG_MPC831x          MPC831x specific
+       CONFIG_MPC8313ERDB      MPC8313ERDB board specific
+
+4.     Compilation
+
+       Assuming you're using BASH (or similar) as your shell:
+
+       export CROSS_COMPILE=your-cross-compiler-prefix-
+       make distclean
+       make MPC8313ERDB_33_config
+       (or make MPC8313ERDB_66_config, depending on the speed of
+        the oscillator on your board)
+       make
+
+5.     Downloading and Flashing Images
+
+5.1    Reflash U-boot Image using U-boot
+
+       =>run tftpflash
+
+       You may want to try
+       =>tftpboot $loadaddr $uboot
+       first, to make sure that the TFTP load will succeed before it
+       goes ahead and wipes out your current firmware.  And of course,
+       have an alternate means of programming the flash available
+       if the new u-boot doesn't boot.
+
+5.2    Downloading and Booting Linux Kernel
+
+       Ensure that all networking-related environment variables are set
+       properly (including ipaddr, serverip, gatewayip (if needed),
+       netmask, ethaddr, eth1addr, rootpath (if using NFS root),
+       fdtfile, and bootfile).
+
+       Then, do one of the following, depending on whether you
+       want an NFS root or a ramdisk root:
+
+       =>run nfsboot
+       or
+       =>run ramboot
+
+6      Notes
+
+       Booting from NAND flash is not yet supported.
+       The console baudrate for MPC8313ERDB is 115200bps.
